The dataproducts interface is a 50 pin connector and different control set.
On Gould/Encore computers I usually divert the printout to a serial line and capture/convert that to postscript. Occasionally I don't have any spare serial lines.
So I have a dataproducts to centronics converter
https://www.photologic.ca/dc1.htm That has a bug that I may (after many years) have found a fix for. - notice it costs 10x the retroprinter!
I tested another computer recently with the above converter and the retro - it captured the data but I need to experiment with the emulations (I only tried IBM).
